Email ID: gopinath4010gmail.com ABSTRACT: A wind turbine is a rotary device that extracts energy from the wind. Wind energy has been shown to be one of the most viable sources of renewable energy. With current technology‚ the low cost of wind energy is competitive with more conventional

1. Identify each of the following statements as either true or false. If false‚ explain why. (a) Viscosity is a measure of how easily a fluid flows. (b) Although important‚ fluids are not essential to many living things. (c) A meniscus forms when water particles adhere to the sides of their container. (d) Buoyancy‚ like water pressure‚ acts in all directions. 2. Describe the relationship between mass‚ volume‚ and density of matter. 3. Use the particle theory to explain the differences between

Experiment 3: Fluid Flow Friction and Fitting Loss Objective To determine the pressure or head loss in different diameters pipes‚ joints and valves Theory Pipe flows belong to a broader class of flows‚ called internal flows‚ where the fluid is completely bounded by solid surfaces. In contrast‚ in external flows‚ such as flow over a flat plate or an airplane wing‚ only part of the flow is bounded by a solid surface. The term pipe flow is generally used to describe flow through round pipes

FLUID MECHANICS Fluids mechanics is a branch of mechanics that is concerned with properties of gases and liquids. Mechanics is important as all physical activities involves fluid environments‚ be it air‚ water or a combination of both. The type of fluid environment we experience impacts on performance. Flotation The ability to maintain a stationary on the surface of the water- varies from he on person to another. Our body floats on water when forces created by its weight are matched equally

Lecture No. 5 CLASSIFICATION OF FLUID FLOW AND THE CONTINUITY EQUATION 5.1 Classification of Fluid Flow Uniform flow If the velocity of the fluid is the same in magnitude and direction at every point in the fluid the flow is said to be uniform. Non-uniform flow A non-uniform flow is one where the velocities at different points at a given instant are not the same. Every fluid that flows near a solid boundary will be non-uniform because the fluid at the boundary takes the velocity of the

of the drag force on a circular cylinder. The devices used in this experiment were a fan‚ closed-channel venturi-shape pipe‚ a Pitot tube‚ circular cylinder with holes of different angles‚ U-tube manometers and a barometer. INTRODUCTION When a fluid is passing through an object‚ it produces a total force on the object. This force is a combined force of lift and drag forces (Anderson 2007). External flows past objects have been studied extensively because of their many practical applications. For

CBE 6333‚ R. Levicky 1 Potential Flow Part I. Theoretical Background. Potential Flow. Potential flow is frictionless‚ irrotational flow. Even though all real fluids are viscous to some degree‚ if the effects of viscosity are sufficiently small then the accompanying frictional effects may be negligible. Viscous effects become negligible‚ for example‚ for flows at high Reynolds number that are dominated by convective transport of momentum. Thus potential flow is often useful for analyzing external
